Compiler Error C2782

'declaration' : template parameter 'identifier' is ambiguous

Remarks

The compiler cannot determine the type of a template argument.

Examples

The following example generates C2782:

// C2782.cpp
template<typename T>
void f(T, T) {}

int main() {
   f(1, 'c');   // C2782
   // try the following line instead
   // f<int>(1, 'c');
}

C2782 can also occur when using generics:

// C2782b.cpp
// compile with: /clr
generic<typename T> void gf(T, T) { }

int main() {
   gf(1, 'c'); // C2782
   // try the following line instead
   // gf<int>(1, 'c');
}
